6. Brew group display

Brew group display description

Once the brew group reaches the pre-set temperature after the machine is switched on, the following screen is shown on each of the individual brew group displays.

The following information is displayed:

• CHRONOMETER: Total effective brewing time.
• T: Pre-set temperature of the brew group.
• W: Total water weight supplied by the brew group.
• F: Real time flow in grams/second of the water supplied by the brew group.

There is also a yellow button available which can be configured to carry out different functions. By default it is set to activate a quick 1.5s flush of water to clean the shower of any remaining coffee residue.

If the brew group is powered OFF by means of the special menu on the machine's

main display, the screen will no longer display the above parameters and only the word OFF will appear as shown in the image below.

When the brew group is switched back ON, all parameters will flash until the pre-set temperature is reached.

Scale

During a brewing operation, in addition to displaying the total weight of the water used (item W), it is possible to measure the weight of the water delivered to the cup.

By tapping the P3 button (YELLOW button on the touch-screen) of the relevant group DURING the BREWING PROCESS the grams of water delivered from that moment on is displayed.

This function is used, for example, to measure the coffee in the cup when pressed exactly when the first drops of coffee are delivered.

7. Preparing an espresso coffee

To always make a quality coffee keep the portafilters (10 Fig.2) inserted in the brew groups (9 Fig.1) so as to maintain them at the proper temperature.

To prepare an espresso coffee follow the procedure below:

• Unhook the desired portafilter, avoiding hot metal parts.
• Clean the filter inside the portafilter of any coffee residue.
• Load the filter with fresh coffee with the proper grind size (1 dose of coffee for a single filter, 2 doses of coffee for a double filter).
• Firmly press the coffee with the special manual coffee tamper supplied.
• Clean any residual coffee from the edge of the filter and reattach the portafilter to the brew group.
• Press one of the 2 buttons for the automatic dosage (P0 or P1 Fig.3) of the relevant brew group.

WARNING

Avoid putting your hands under the brew groups when they are in operation. Do not touch any of the metal parts of the brew groups or portafilters as they may cause burns.

8. Preparing hot milk

Pour some milk into a frothing jug/pitcher equipped with a handle. Insert the steam wand (4 Fig.2) in the jug and open the steam valve (5 Fig.2). When the milk reaches the desired temperature, close the steam valve. Once this operation is complete, clean the steam wand with a damp cloth to prevent milk residues from accumulating on it. Afterwards, discharge some steam on the grid of the tray to clean the inside of the wand from milk residues. Protect yourself from the spray with the damp cloth.

WARNING

To manoeuvre the steam wand, use the special insulating handle. Do not open the steam valve without having placed the steam wand in the jug to avoid possible burns.

NOTE

To obtain good quality milk froth it is necessary to follow a specific procedure when warming the milk. This procedure can be learnt from specific video training courses. For safety reasons it is not described in this manual.

9. Hot water supply

This machine is equipped with two hot water dispensing buttons for infusions, dosed by time. Place a container (resistant to temperatures of at least 125 °C) under the hot water outlet (6 Fig.2) and press one of the two hot water supply buttons (P5 or P7 Fig.3). During installation, it is possible to program the quantity and temperature of water to be delivered by each of the aforementioned buttons; this programming must be performed only and exclusively by the installer.

WARNING

Do not press the hot water buttons before placing a container under the outlet so as to prevent burns.

10. Use of the cup warmer

In particular environmental conditions around the equipment, the circulation of cold air may compromise and deviate the normal flow of hot air from the boiler towards the cups, and therefore prevent them from reaching the proper temperature.

The use of cups that are not sufficiently heated when an espresso is pulled may lead to the instantaneous loss of about 25-35 °C and a resulting lukewarm espresso.

The cup warmer built into this machine is electrically powered and can be switched on and off with the P4 button (Fig.3). Only the rear portion of the cup warming tray heats up.

The inverted cup icon is displayed on the screen when the cup warmer is switched on.

The cup warmer has 2 settings: by pressing the P4 button once, the cup warmer operates intermittently providing a medium level of heat. In this case, the cup warmer icon on the display flashes.

By pressing the P4 button a second time, the maximum heating setting is activated and the icon on the display remains fixed.

To switch off the cup warmer, press the P4 button again. At this point, the icon on the display disappears.

11. Use of the MCS

The MCS (Milk Control System) is an automatic milk heating system.

With the MCS it is possible to froth milk at a pre-set temperature. The frothed milk obtained is comparable to that of the best baristas. Using the MCS is as simple as putting a quantity of cold milk in a jug, placing it under the MCS wand, and pressing the P6 button (Fig.3). When the milk has reached the preset temperature (programmed during the installation of the machine), the steam supply will stop automatically and the frothed milk will be ready for use.

WARNING

Do not use the MCS with the steam wand facing the operator or another person.

NOTE

The proper operation of the MCS requires the good cleaning of the steam wand and its nozzle after each use. Depending on the use of the MCS it is also advisable to disassemble the steam nozzle at least twice a day and wash it properly before reinstalling it.

To obtain quality frothed milk it is advisable to pour a quantity of milk in the jug sufficient to cover the end of the steam wand and place it inclined against the wall of the jug to facilitate the formation of a vortex during the heating process.

12. Flow regulation

The machine is equipped with a MFR (Manual Flow Regulator) system that allows the regulation of the water flow supplied by each brew group. To adjust the flow, use the tool featuring a hexagonal end which is incorporated in the special coffee tamper supplied with the machine.

The procedure below shows how to regulate the flow appropriately:
